LAND AND FRESHWATER MOLLUSCA. 363 



towards the edges of the mantle, foot and tail — more vivid than 

 is the case with any var. of hortensis. 



A. hortensis, Ferussac. — Very abundant and generally dis- 

 tributed. In addition to the ordinary grey and striped form, 

 specimens of various yellow, buff, brown, and whitish hues 

 also occur. 



Limax flavus, Linn. — I have had no opportunity of meeting 

 with this slug at Oxford, but doubtless it is still common in 

 cellars, as mentioned in Mr. Whiteaves' list. 



L. agrestis, Linn. — Common everywhere. 



L. Icevis, Muller. — Not uncommon around Oxford under stones 

 and logs of wood in very wet places ; by streams at South 

 Hincksey, by Botley, at Wytham, and in Wick Copse. Unmis- 

 takably distinct from L. agrestis. 



L. arborum, Bouchard-Chantereaux. — Rather local, being 

 generally confined to beech-trees, which are not very plentiful in 

 the immediate neighbourhood of Oxford. On beeches in wood on 

 Wytham Hill and at Stonesfield. At Cumnor I found it in the 

 rather unusual locality of a loose-stone wall. During hybernation 

 this slug loses colour and becomes quite pale. I have it also from 

 the more distant localities of Kingham, near Chipping Norton, 

 and Goring ; while Mr. Whiteaves records it from Watlington. 



L. maximus, Linn. — I have not been fortunate enough to find 

 this species. Mr. Whiteaves, writing of it under the name 

 cinereus, says that it is remarkably scarce in the immediate 

 vicinity of Oxford, but is very large and abundant in the southern 

 parts of the county. 



Fam. II. Testacellid^:. 



Testacella haliotidea, Drap.— Occasionally met with in digging 

 in vegetable gardens around Oxford, especially on the eastern 

 side of the city. A specimen preserved in the University Museum, 

 and added to Mr. Whiteaves' collection, was found " in a garden 

 on Headington Hill," and I have received live specimens from a 

 cabbage-field near St. Clement's Church. 



Fam. III. Helicid^. 



Succinea putris, Linn. — Common on plants by rivers, streams 

 and ditches. The most usual place where this and the following 

 species hybernates is under the bark of pollard-willows that border
